The International Centre for Underwater Archaeology (ICUA) is once again organising courses in the restoration and conservation of underwater archaeological finds to be held in Zadar, Croatia in the period from February - June 2019.This international course is targeted to the practical and theoretical training of candidates for independent work in the restoration and conservation of underwater archaeological finds.The courses will consist of practical work under the supervision of a mentor at the workshops of the International Centre for Underwater Archaeology (ICUA) in Zadar. Candidates will have the opportunity to select work on the various materials treated at the three main workshops that deal with metal, ceramic and glass, and organic finds. Training will be provided by ICUA Zadar staff, pursuant to the course programme manual and the standards valid for the ICUA/UNESCO advanced course staged in 2011. Candidates can choose from a number of modules. We are planning a one-month Advanced Course that can be staged in one of the three main workshops, or a two-week Introductory Course that will involve work in all three workshops.At the end of the course candidates will take an exam on the theoretical and practical segments, after which they will be entitled to a certificate confirming that they have passed our Centre's course for specialised conservators/restorers of underwater archaeological finds.

Course Programmes

Advanced Course on the Conservation and Restoration of Archaeological Finds

A one-month course on the conservation and restoration of underwater archaeological finds made of ceramic and glass, metals and organic materials will be staged at the ICUA Zadar Restoration and Conservation Department. Participants may choose one workshop: for ceramic and glass finds, the metal finds workshop, or the workshop on finds of organic materials – as desired. The advanced programme for each of the workshop courses runs for a month. These courses provide for an individual mentored approach to each participant based on their capabilities and knowledge in the field of conservation and restoration. This advanced course consists of theoretical and practical (hands-on) training that will offer inexperienced participants the fundamental knowledge required in undertaking conservation-restoration treatment of artefacts made of a given material, while for the more experienced it aims to broaden and enrich knowledge and to serve as a venue for the exchange of valuable information and practical knowledge. The practical segment of the training will be conducted on contemporary and original artefacts, depending on the capability and knowledge of applicants and on the complexity of the operations involved, where unpractised execution could cause irreparable damage to original artefacts. All course participants will also receive their copy of the manual on the restoration and conservation of underwater archaeological finds published by the International Centre for Underwater Archaeology in Zadar. In the manual you will find all of the fundamental guidelines for the treatment of archaeological finds originating from underwater research.

Introductory Course on the Conservation and Restoration of Archaeological Finds

The two-week course on the conservation and restoration of underwater archaeological finds provides an introduction to conservation-restoration. During the course participants will be acquainted with work on all materials and spend a few days in each of the workshops. The training consists of a theoretical and practical segment, with the possibility of placing greater focus on a given segment, depending on the wishes, capabilities and knowledge of the applicant. The programme will be conducted along the same points as the one-month course, but in lesser scope, based on the time available. In the practical segment applicants will have the opportunity to try their hand on the phases of conservation-restoration work that can be executed in the available time. Within these time constraints conducting all phases of conservation-restoration work on a single object is impossible and participants will therefore have the opportunity to work on phases of conservation-restoration work on various smaller objects. The goal of this brief course is to either acquaint participants with conservation and restoration as a method of protecting archaeological finds or to acquaint more experienced conservators-restorers with the specifics pertaining to the treatment of archaeological finds originating from wet environments.
